Dear All: Since IPv6 is using the root DNS server in Ipv4 to search the DNS in the Internet.
It means that the Ipv4 only client Host may get a host name resolved but with IPv6 address. Assume that it is a pure Ipv4 client host, and the Ipv6 Host only have IPv6 DNS record in the Ipv4 DNS server. ( i.e. No Ipv4 DNS reccord). The Ipv4 client host should got Host not find on that host domain Name . It will be a problem when transition Ipv4 network to Ipv6 network. Becasue we shall not want to keep the Ipv4 address mapping record in Ipv4 DNS server when we transition to Ipv6 network. However , do not keep DNS Ipv4 address mapping record in DNS server will disconnect all the current host/server visiting by the Ipv4 only client host form internet ( can not resolve DNS). This problem will post a strong resisit to transition form Ipv4 to Ipv6 . Are there any solution on this ? Any comment on this ? K. M.
